Notes:
1. Throw distance does not affect image quality, provided these ranges are taken into account.
2. Only the Signature C, D, E, F and G lenses can be used with the optional CineWide (secondary
anamorphic) lens. Doing so affects the throw distances as shown here.
3. The SC-1 has a native resolution of 2048 x 1080, which is about a 1.9:1 aspect ratio. For 16:9
material, only the 1920 x 1080 area is used which is a 16:9 (1.78:1) aspect ratio. Most often, the
16:9 throw distance will be used. If used with CineWide or CineWide with AutoScope, only the
16:9 area will be used.
